<a href="https://npgsweb.ars-grin.gov/gringlobal/accessiondetail.aspx?1829978">RSD 1991001</a> and <a href="https://npgsweb.ars-grin.gov/gringlobal/accessiondetail.aspx?1829979">RSD 1991002</a> were seed lots collected in Vietnam (see Source History). Due to inconsistent propagations a number of years ago, certain selections of RSD 1991001 were renumbered as <a href="http://www.ars-grin.gov/cgi-bin/npgs/acc/search.pl?accid=RSD+1991%25andinactive=Yes">RRUT 92 - RRUT 98 </a>. Only one seedling of RSD 1991002 germinated, and it was renumbered as <a href="https://npgsweb.ars-grin.gov/gringlobal/accessiondetail.aspx?1829980">RRUT 99</a>. Seedlings and grafted propagations are maintained in the field in RIverside and Thermal (California) for observation and evaluation. (RR Krueger, 02/12/2010)
